Power supply device with rollers

Abstract

Provided is a power supply device with rollers. The power supply device comprises a pin-type insertion unit (3) and a seat-hole type fixing unit. The pin-type insertion unit (3) comprises a unit body part (30) and two pin-type plugs (31) which are symmetrically arranged relative to the central axis of the unit body part (30). The upper part of each pin-type plug (31) is provided with a horizontal guide part (33) for slidingly being in slide fit with a corresponding one of two slide grooves (32) in the unit body part (30) and for bearing the force load in the vertical direction. The seat-hole type fixing unit comprises a base (1) and two mounting racks (4) which are fixed on the base (1) and are symmetrically arranged relative to the central axis. Each mounting rack (4) is provided with a slot (40) therein for insertion of the corresponding one of the two pin-type plugs (31).

Description

technical field [0001] The invention relates to the field of electric power supply, in particular to electric power supply equipment with rollers. Background technique [0002] In the field of electric power supply, the cooperating use of the pin type insertion device and the socket hole type fixing device is a common mode. [0003] In this power supply mode, the pin is often clamped by elastic clamping force to achieve reliable electrical connection. However, this mode can meet the general requirements, but it is difficult to meet the high reliability of the clamping force. In some cases where the clamping degree of the power supply plug is required to be high, some additional fixing force is often required to achieve a reliable connection, which often requires a very complicated mechanism to achieve. [0004] Moreover, the distance error between the pins and the seat holes due to manufacturing errors or use factors often makes it difficult to insert or the clamping force...

Problems solved by technology

However, this mode can meet the general requirements, but it is difficult to meet the situation of high clamping force reliability

In some situations where the clamping degree of the power supply plug is required to be high, some additional fixing force is often required to achieve a reliable connection, which often requires a very complicated mechanism to achieve

[0004] Moreover, for the distance between the pins and the distance between the seat holes, the distance error caused by manufacturing errors or use factors often makes it difficult to insert or the clamping force is weakened after insertion, which in turn affects the power supply stability.
